In this scenario, the person’s systemic blood pressure is
abnormally high. This blood pressure is not within the normal range
for renal autoregulation. As a result, glomerular filtration rate
(GFR) cannot be returned to its normal rate. Consequently, the GFR
is very high.

Step 2 of 6

The high glomerular filtration rate (GFR) could exert strong
forces on the glomerular blood. This strong force could force
abnormally bigger molecules into the capsular space. So, the high
GFR filters the plasma proteins during filtration.

Step 3 of 6

Normally, plasma proteins are too big to enter the filtrate. The
renal tubule’s filtration membrane could not reabsorb these plasma
proteins into the blood. As a result, the proteins are present in
urine.

Hence, the correct option is (b)excessive amount of plasma proteins are
filtered at the renal corpuscle.

Step 4 of 6

Protein is not a normal component of urine. The presence of
protein signals problems. In this scenario, the problem is high
blood pressure. This high blood pressure may be the result of
increased blood volume or increased concentration of certain
ions.

Hence, the option (a) protein is not a normal component
of urine is incorrect.

Step 5 of 6

Tubular cells line the lumen of the renal tubule. The main
functions of the tubular cells are reabsorption and secretion.
Tubular cells produce transport proteins. These transport proteins
are embedded in the membranes of the tubular cells. These transport
proteins do not become part of the tubular fluid. Consequently,
these transport proteins should not be present in urine.

Proteins are usually big molecules. The filtration membrane
filters very small molecules. In addition, plasma proteins are
nutrients for cells. The function of the kidney is to eliminate
waste products. During the process, the nephrons retain nutrients.
In addition, molecules enter tubular fluid during secretion.
Secretion is via transport proteins. The tubular cells do not
exocytose proteins into tubular fluid.

Hence, the option (d) tubular cells have exocytosed
protein into the tubular fluid is incorrect.
